It is important that negotiated and agreed commitments (i.e., service level agreements [SLAs]) can be fulfilled all the time. If this were not achievable, IT should not have agreed to these requirements, as entering into such a commitment would be misleading to the business. 'All the time' in this context directly relates to the 'agreed obligations' and does not imply that a service has to be available 100 percent of the time. Costs are a result of availability and service continuity management and may only be partially controllable. These costs directly reflect the agreed upon obligations. Capacity management is a necessary, but not sufficient, condition of availability. Despite the possibility that a lack of capacity may result in an availability issue, providing the capacity necessary for seamless operations of services would be done within capacity management, and not within availability management. Generating reports might be a task of availability and service continuity management, but that is true for many other areas of interest as well (e.g., incident, problem, capacity and change management).

The best method to prevent wire transfer fraud by bank employees is system-enforced dual control. System- enforced dual control is a segregation of duties control that requires two or more individuals to perform or authorize a transaction or activity using a system that enforces this requirement. System-enforced dual control can prevent wire transfer fraud by requiring independent verification and approval of payment requests, amounts, and recipients by different bank employees using a system that does not allow any single employee to complete the transaction alone. The other options are not as effective as system-enforced dual control in preventing wire transfer fraud, as they do not involve independent checks or approvals using a system.
Independent reconciliation is a detective control that can help compare and confirm payment records with bank statements, but it does not prevent wire transfer fraud from occurring. Re-keying of wire dollar amounts is an input control that can help detect any errors or discrepancies in payment amounts, but it does not prevent wire transfer fraud from occurring. Two-factor authentication control is an access control that can help verify the identity and authorization of bank employees, but it does not prevent wire transfer fraud from occurring.

Explanation:
A DBA only in rare instances should be mapping data elements from the data model to the internal schema (physical data storage definitions). To do so would eliminate data independence for application systems.
Mapping of the data model occurs with the conceptual schema since the conceptual schema represents the enterprise wide view of data within an organization and is the basis for deriving and end-user department data model.
